Universal Finite-size Scaling Functions with Exact Non-universal Metric Factors

Abstract

Using exact partition functions and finite-size corrections for the Ising model on finite square, plane triangular, and honeycomb lattices, we obtain universal finite-size scaling functions for the specific heat, the internal energy, and the free energy of the Ising model on these lattices with exact non-universal metric factors.
